I found a copy of the model in russian unfortunately I can't read russian but the illustrations speak for themselves and the book is quiet good. BTW One of Mortensens books "The new projection control" is available for download on the internet archive. http://www.archive.org/details/newpr...oncon000727mbp it's not a posing book though.

Go to http://books.google.com/. On the search line type a subject such as Photography, or Camera, etc; and the press the Search Books button.

Then on the left-side of the page containing the search results, select the "Free Google eBooks" option. Most, if not all of the books listed will be downloadable in their entirety. You can use Acrobat Reader for the books you collect that are in PDF format.
